Voice Control
Signals
You can view real-time voice signalling bit information in the Voice
Control Signal Display, see
T1 standards define the use of four signalling bits (designated
A,B,C and D) for setting up and supervising telephone calls.
In most cases today only the first two bits, A and B, are used for
call setup. Bits C and D are still available for historical and
standards compliance reasons.
The signalling bits indicate conditions such as:
• Receiver off-hook and requesting dial tone
• Incoming call (ring)
• Call in progress (busy)
• Line idle (available)
The Voice Control Signal Display
shows the status of the
signalling bits for each of the 24 timeslots (DS0s) in the selected
T1.
